Aechmophorus occidentalis (Western Grebe)

Wikipedia Abstract

The western grebe (Aechmophorus occidentalis) is a species in the grebe family of water birds. Folk names include "dabchick", "swan grebe" and "swan-necked grebe".Western grebe fossils from the Late Pleistocene of SW North America were described as a distinct species, but later ranked as a paleosubspecies Aechmophorus occidentalis lucasi. More recent study found them to fall within the variation now known to exist in today's birds.
